Hi Lee,
First, sorry about the delay in answering, as I was in Sacramento teaching all weekend. BTW, I will be in Seattle in 2 weeks at the SeaTac Marriott doing our course, and would love to see you for dinner! Let’s talk. Anyhow, I use the C-6 tip, and it’s highest wattage rating is 4W which is why I use it at 4, BUT becuase of it’s continual taper, it delivers like 6! Nice tip. You also stated that “Is the decision to change the W related to patient becoming uncomfortable, or is it the surface texture that you are trying to affect? ie: lower W for smoother surface. Or is it control for margin refinement and placement? ” And I reply, that it is all of the above, except patient becoming uncomfortable. Mostly, as you learn how to use the laser effectively for crowns/veneers, you learn what wattages work for margination, smoothing, etc….and that is what I vary based upon the desired outcome/effect I am looking for in the lasers use. Make sense? I will show you when I see you. I look forward to talking with you soon!
